be quiet! Pure Loop 3 360mm Liquid CPU Cooler

The be quiet! Pure Loop 3 360mm delivers high-performance liquid cooling with exceptionally quiet operation for overclocked systems. Designed for users who demand serious cooling power without the noise, this all-in-one water cooling solution handles all consumer CPUs with ease.

Advanced Cooling Performance

The Pure Loop 3 features a state-of-the-art PWM pump with a 6-pole motor that reduces vibrations to an absolute minimum. The pump operates at speeds between 3000-5500 RPM, providing adjustable cooling performance through standard 4-pin PWM control. Three Pure Wings 3 120mm PWM high-speed fans deliver 59.6 CFM airflow at 2100 RPM maximum speed, generating 2.41 mm H2O static pressure for efficient heat dissipation through the aluminum radiator.

Silent Operation

Noise levels remain impressively low across all operating speeds: 17.6 dB(A) at 50% speed, 29.3 dB(A) at 75%, and just 37.2 dB(A) at full speed. The fans utilize rifle bearing technology with a 4-pole motor and closed-loop design, featuring funnel-shaped air outlets that maximize static pressure while maintaining quiet operation. Each fan is rated for 80,000 hours lifespan at 25°C.

User-Friendly Design

Installation is straightforward with included mounting hardware for Intel (1851/1700/1200/1151/1150/1155) and AMD (AM5/AM4) sockets. The flexible sleeved tubes measure 400mm in length, providing ample reach for various case configurations. Daisy-chained PWM fans simplify cable management, requiring only a single motherboard header connection. An easy-access refill port allows for convenient maintenance and coolant replenishment when needed.

Build Quality and Reliability

The copper base plate ensures optimal thermal transfer from the CPU, while the 397 x 120 x 27mm aluminum radiator efficiently dissipates heat. The cooling block measures 68.5 x 93.4 x 44.9mm with a clean, understated aesthetic that fits any build. The complete unit weighs 1.250kg and includes thermal grease, mounting hardware for both platforms, and a 4-pin PWM extension cable. Backed by a 3-year manufacturer's warranty and conceived, designed, and quality-controlled in Germany, the Pure Loop 3 meets CE, UKCA, and FCC safety certifications.
